- * Button support.
- *
- * Description:
- *   up_buttoninit() must be called to initialize button resources.  After
- *   that, up_buttons() may be called to collect the current state of all
- *   buttons or up_irqbutton() may be called to register button interrupt
- *   handlers.
- *
- *   After up_buttoninit() has been called, up_buttons() may be called to
- *   collect the state of all buttons.  up_buttons() returns an 8-bit bit set
- *   with each bit associated with a button.  See the BUTTON_*_BIT
- *   definitions in board.h for the meaning of each bit.
- *
- *   up_irqbutton() may be called to register an interrupt handler that will
- *   be called when a button is depressed or released.  The ID value is a
- *   button enumeration value that uniquely identifies a button resource.
- *   See the BUTTON_* definitions in board.h for the meaning of enumeration
- *   value.  The previous interrupt handler address is returned (so that it
- *   may restored, if so desired).
- *
- *   When an interrupt occurs, it is due to a change on the GPIO input pin
- *   associated with the button.  In that case, all attached change
- *   notification handlers will be called.  Each handler must maintain state
- *   and determine if the unlying GPIO button input value changed.
